  • env_list_variables - Parse a .env file and list all variable keys (values masked)
  • env_detect_missing - Check if required environment variables are present and populated
  • env_compare_files - Compare .env vs .env.example to find missing or extra variables
  • env_find_duplicates - Find duplicate variable keys in a .env file
Environment Generator
  • env_generate_example - Generate .env.example from an existing .env file (strips values, keeps comments, adds placeholders)
  • env_detect_from_package_json - Detect environment variables referenced in package.json scripts
  • env_detect_from_docker_compose - Detect environment variables referenced in a docker-compose.yml file

  • port_check - Check if a specific port is in use and identify the process
  • port_find_available - Find available ports within a given range
  • port_list_processes - List processes using specific ports
System Info
  • system_info - OS, CPU, memory, disk, Node/npm/Python/Git/Docker versions
Dependency Checker
